So, I'm leaving those as they are for now.

Mmm… I've added a new phase to patch the `setup.py`, but couldn't get
the version variable to work. Sorry for my… noobiness!? ^_^'

```
;; version.txt is not included in notmuch, so we patch in the version number
(add-after 'create-notmuch-config 'patch-setup.py
  (lambda _
    (substitute* "setup.py"
      (("with open\\(NOTMUCH_VERSION_FILE\\) as fp:") "")
      (("    VERSION = fp.read\\(\\).strip\\(\\)") "")
      (("version=VERSION,") (string-append "version='" "0.0.0" "',")))))
```

I've tried to replace `0.0.0` with `version` or `,version` but that
doesn't seem to be the proper way to do it.

Regards,
